Of these potential actions to reduce emission reductions, PSCAA has found that a clean fuel standard would have the largest potential to reduce greenhouse gas emissions and provide other air quality benefits.

The standard would be market-based, allowing for innovation and flexibility. California, Oregon and British Columbia have already established clean fuel standards.

Under a new rule by the Washington Department of Ecology, all new vehicles licensed in Washington will continue meeting California’s standards, which would progressively reduce the amount of greenhouse gases that cars and trucks emit through 2025.
